- Fly fishing. Altenbach, J. Scott // National Wildlife (World Edition);Oct/Nov94, Vol. 32 Issue 6, p50
Features the fishing bat. Presence in Latin America; Anatomy's suitability for fishing; Use of ultrasonic sound waves to detect a target.
- Extinction of populations by inbreeding depression under stochastic environments Tanaka, Yoshinari // Population Ecology;Apr2000, Vol. 42 Issue 1, p55
Inbreeding depression may induce rapid extinction due to positive feedbacks between inbreeding depression and reduction of population size, which is often referred to as extinction vortex by inbreeding depression. The present analysis has demonstrated that the extinction vortex is likely to...
- No More Gorillas? McClure, Laura // Weekly Reader News - Senior;10/26/2007, Vol. 86 Issue 8, p4
This article focuses on the risk of extinction for male western lowland gorillas. These gorillas possess the strength of four to eight humans, however, they are vulnerable to hunters and disease. The species is predicted to be extinct by 2019. On the 2007 IUCN Red List of Threatened Species, the...
- Long-term demographic analysis in goshawk Accipiter gentilis: the role of density dependence and stochasticity. Krüger, Oliver // Oecologia;May2007, Vol. 152 Issue 3, p459
Density dependence and environmental stochasticity are both potentially important processes influencing population demography and long-term population growth. Quantifying the importance of these two processes for population growth requires both long-term population as well as individual-based...
- Contribution of Inbreeding to Extinction Risk in Threatened Species. Brook, Barry W.; Tonkyn, David W.; O'Grady, Julian J.; Frankham, Richard // Conservation Ecology (11955449);2002, Vol. 6 Issue 1, p69
The article presents a study which evaluated the role of inbreeding in extinction using realistic population viability analyses of threatened species, with and without inbreeding depression. The major variable which explains differences among species was initial population growth rate while the...
- Are We Underestimating Species Extinction Risk? Drake, J. M. // PLoS Biology;Jul2005, Vol. 3 Issue 7, p1154
The article presents information related to the loss of biodiversity. In 2004, the World Conservation Union reported an unprecedented decline in biodiversity, with nearly 16,000 species facing extinction. Standard models for predicting extinction assume that population growth and decline are...
- Endangered Animals Get Help. // Scholastic News -- Edition 1;Apr2001, Vol. 57 Issue 7, following p4
Suggests solutions in order to prevent the extinction of several endangered animals.
- Endangered species. // World Almanac for Kids;1996, p23
Provides information about endangered, or threatened, animal species. The number of species that are endangered as of 1996; How climate changes, habitat destruction and over-hunting contribute to animal extinction.
- ON THE BRINK. Masibay, Kim Y. // Science World;1/10/2003, Vol. 59 Issue 7, p4
Discusses the causes of possible extinction of Iberian lynx, red-shanked Duoc Langur monkey and other plant and animal species.
